问题描述

我按照教程在 RealTime Database 和 Android 应用程序之间传输数据。但是当我在这里启动应用程序时是我的 LogCat ：

如您所见，我的 API 有错误，但服务器位置也有错误，我从比利时搬到了美国北部（在 Firebase 上）。

解决方案

您没有提供任何参考此代码的代码。所以让我告诉你解决这个问题的可能方法。由于您告诉您正在学习教程，因此他们使用的 google API 版本可能已经过时。检查您的 build.gradle 文件并在必要时更新依赖项。

classpath 'com.google.gms:google-services:4.3.10'

另一种解决方案是检查 google-services.json 文件中的 API 密钥是否与 firebase 中的 API 密钥匹配。无论哪种方式，只需再次删除并粘贴文件，然后构建您的应用程序。
